The Deichtorhallen Hamburg are showing the largest solo exhibition of the artist Katharina ­Sieverding to date on four floors of the Falckenberg Collection. Around 120 works span all ­phases of the artist’s oeuvre. For more than five decades, Katharina Sieverding has been one of the pioneers who recognized the diverse expressive possibilities of photography early on and ­continually expanded the medium conceptually and formally. Her subjects and artistic principle are "transformation processes, questions about identity, gender, and race," as she states. She became known for the unprecedented consistency with which she has used her portrait, enlarging and manipulating it in a variety of ways, in film and photography since the 1960s. Beginning in the 1970s she worked on large-format montages on the state of the world, first shown internationally at documenta 6 in 1977. The exhibition as well as the book places a special focus on the unbroken high topicality of earlier works and the artist’s ­interest in creating instal­lative approaches to the medium of photography.
